The results of five different spatial domain discretizations and two turbulence models (k-ω SST and k-ε RNG) have been compared, in order to gain the optimal y+ parameter distribution along the blade walls during a full rotor revolution. The resulting optimal mesh has appeared to be quite similar to that obtained for the numerical analysis of a vertical-axis wind turbine.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {6}, number = {4}, year = {2012}, pages = {763 - 770}, ee = {https://publications.waset.org/pdf/2388}, url = {https://publications.waset.org/vol/64}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 64, 2012}, }
